...An approach based on discretization techniques with necessary conditions to obtain approximate optimal control and the state for optimal control problems (with non-linear delay systems) was proposed in Gollman et al. (2009), but achieving the necessary conditions in some problems and the implementation of the approach may be faced with difficulties. Koshkouei et al. (2012) proposed a method based on measure theory, functional analysis and linear programming and extended it in order to optimize a definite objective function, and to design an appropriate optimal control for the non-linear time-delay systems....

Recently, Marzban & Hoseini (2015) considered numerical treatment of non-linear optimal control problems. Orthogonal functions (OFs) and polynomial series have received considerable attentions in dealing with various problems of dynamic systems (Marcellan & Assche, 2006). For such kind of problem, the approach is that of converting the underlaying differential equation governing the dynamical system to an algebraic form through the use of an operational matrix of integration which can be uniquely determined based on the particular OFs. Special attentions have been given to applications of orthogonal functions in solving control or optimal control problems. For example, in Lo et al. (2009), Palanisamy & Rao (1983), Walsh functions are used to solve linear delays control problems, the applications of block-pulse functions in control systems are considered in Deb et al....
